I need some girls opinions on this.

This guy I’ve been talking to you for just a short period of time is in the army, he is 4 states over & sometimes it’s really hard. We can go hours without talking rare 5-10 minute phone calls I totally understand how busy he must be but that’s not the problem.

He is older, he has gone through a divorce so he’s been through more things than me. We’ve started developing some sort of feelings for each other & he’s made is known how he feels about me kinda. He’s told me he wants this to work, I’m the one he wants to wake up too every morning he’s coming back to Texas in 9 months! So that gives me so type of hope

But, last night he texted me saying “I’m so sorry, I have to go ghost for a bit. I’m sorry.” I was like so confused? So I just said “it’s okay.” He texted me this morning with a dry ass “hey” so he went on to tell me he had something happen last night with his family back in Texas which made him upset, so I said “you’re fine don’t even worry about it, but if there’s ever anything you wanna talk about just tell me” he said “I know, I just don’t want to be too vulnerable. Not yet”

I honestly didn’t even know how to take that because I’ve never had anybody say that too me. Idk if it’s just me but I have this tendency to dwell on things. I try to read between the lines & try to figure out the message behind the text (it’s super annoying) so idk. It kinda scared me almost like is he having second thoughts now? Should I be mad? Do I put my wall back up because I’m basically wearing my heart on my sleeve for this guy. I don’t have a lot of “dating” experience nor do I have like a big sister to ask so I’d really like for someone to just talk to me. Give me some advice on this, because I honestly have no idea wtf I’m doing.
